APPARATUS FOR RAISING LIQUIS.

SPEGlFIGATIONforming part of Letters Patent No. 726,359, dated April 28, 1903.

Application filed October 30, 1901. Serial No. 80,579. (No model To all whom it may concern:

Be it known that LVITUS SCHWANINGER, a subject of the King of Bavaria, residing and having my post-oflice address at Oggersheim, in the Palatinate, Germany, have invented certain new and useful Improvements in or Relating to Apparatus for Raising Liquids,of which the following is a specification.

The present invention relates to an apparatus for raising liquids, especially acids, in which when a vessel or chamber has been filled with the liquid to be raised the device shutting off the pressure agent (steam, conipressed air, or the like) is opened by means of a float, by which the said device is closed again toward the end' of the period of pressure.

The annexed drawing represents a vertical section of the apparatus.

The pressure-chamber1 is connected by the pipe 2, controlled by the antireturn-valve 3, with the supply-pipe 4.- of the liquid to be raised and by the valve 5 with the conduit 6 of the pressure agent. The air-discharge valve 7 connects the interior of the pressure-chamloer l withthe outer atmosphere. The pipe 2 is connected near the valve 3 with the pipe S, which leads to the tank 9; The iioat controlling the valve 5, which shuts off the pressure agent, consists of two parts lO and 11, rigidly connected with each other. As will be shown, it is this special construction of the closed hollow float which produces the automatic opening and closing of the valve 5 at the beginning and toward the end, respectively, of the period of pressure, so that the said float forms the principal feature of the present invention.

When a certain degree of over-pressure exists in the pressure-chamber 1, the exhaustvalve 7 is forced thereby against its upper seat 12 and shuts off the interior of the chamber from the outer atmosphere. After the period of pressure when the overpressure has passed out through the pipes 2 and 8 the valve 7 falls back again onto its support 13,

and thus reopens communication between the interior of the pressurechamber and the outer atmosphere, so that the air can pass out of the former when liquid enters.

For the purpose of the following description the weight of the entire Iioat 10 11 will ten kilograms, so that the total load cn the said valve will be thirty kilograms. Assuming, further, that the lower part 10 and the upper part ll of the iioat each displace twentylive kilograms of the liquid to be raised, then when the liquid entering through pipe 4, valve 3, and pipe 2 has entirely covered part 10 of the lioat the valve 5 Will be held closed by a load of thirty minus twentyfive equals five kilograms. The liquid continues to rise, the air contained in the pressure chamber escaping past the exhaustvalve 7 until the upper part 11 of the float is so far immersed in the liquid that the remaining load of five kilograms holding down the valve 5 is also overcome and the latter is opened. The pressure agent in the conduit G now ent-ers the pressure-chamber, closes the exhaust-valve 7, and forces the liquid up through pipe 2 and valve 3 into the conduit The pressure of ten kilograms above the valve 5 being now counterbalanced, the lower part of the float holds the said valve open during the period of pressure with a pressure of twenty-five minus twenty equals five kilograms until the liquid-level has fallen. to the position shown in the drawingthat is to say, to the said lower part. The liquid-level will then have reached the lower end of the pipe 2, so that the pressure in the pressure-chamber Will equalize itself to that of the outer atmosphere through the pipes 2 and S, the exhaust-valve 7 will open, and the process described will begin over again.

' lf it is desired to utilize the expansion of the pressure agent, the shutting off of the latter-that is towsay, the closing of valve 5- must take place before the level of the liquid has fallen to the lower end of pipe 2. For this purpose it is sufficient to place the lower part l0 of the iioat at a relatively higher position--for instance, by loosening the setscrews 15 and 16 and moving the part l0 upward on the rod le. The expansion of the pressure agent will then take place between the closing of valve 5, which takes place sooner than before, and the moment at which the liquid-level reaches the lower end of pipe 2. It may also in some cases be of advantage to make the upper part of the float verroo v tically adjustable by providing it with setscrews 17 18, as shown in the annexed drawing. It is thus rendered possible to exactly limit or control the quantity of liquid to be raised during each operation of the apparatus.

I declare that what I claim is In apparatus for raising liquids the combination of a chamber, means for supplying a pressure agent thereto, a Valve for controlling said supply, an air discharge Valve, means for filling said chamber with liquid and a closed float in said chamber, for coperation with the pressure-supply valve, said float consisting of a lower hollowT body, the buoyancy of said lower hollow body when immersed being greater than its own Weight, insufficient to raise the said valve against the pressure agent, but sufficient to hold it when raised, and an upper hollow body, the buoyancy of said upper hollow body when irn- Inersed being greater than its own weight and adapted to reinforce the lower part to open the said valve against the pressure agent, the float comprising a'` rod attached to said pressure-agent-controlling Valve, two closed hollow bodies adapted to slide on said rod before starting the apparatus and set-screws for securing the float-bodies to said rod, substantially as set forth.

In witness whereof I have signed this specication in the presence of two Witnesses.
